. lll/VENTOR NHED STATES PATENT @Friend JAMES srnivofrr, or CHATHAM, ILLINOIS. 'i

To all 'whom 'imay concern:

1 siding at Chatham, in the countT 'of Sanga- Be' it known that I, JAMES'SINNOTT, re-

mon and Sta-te of Illinois. have invented a.

new and Improved Self-Filler Fountain- -Pein ofI which the following is a specificat-ion.

.lviy invention, .vhich relates generally. to fountain pens, has for its object to provide a simple and inexpensive construction of pen,.lxaving provision for taking up a lling z of writing iuid when dipped therein, suilicienafor some time before the iiuid is exhausted, and. in which other provision is made whereby the ordinary types of pen points may be readily used.

My invention also has for its object.' to provide an improved construction of pen of the general type stated, in which the lead or feed way to the pen point is especially designed, so that the pen will not quickly clog or ,the point become impaired by reason of the ink clotting or drying thereon.v

With other objects in'view that will hereinafter appear, my invention consists in certain details of construction and novel combination of parts that-constitute my pen, all of which will be hereinafter fully describedgfspecically pointed out in the claims and illustrated in the accompanying drawings, .in which:

Figure 1, is a view that shows the manner in which my construction of pen is dipped for filling, and shows the font or lower end in longitudinal section. Fig. 2, is a vertical-section of the lower end of the pen and shows it filled for writing. ,Figs 3, 4 and 5 are cross sections of the pen, taken respectively on the lines 3 3, 4.-1 and 5`5 on Fig. 2. Fig. 6,'is a View that shows the pen, the font or sleeve and the holder .separated. Fig. 7, is a view of a modied form. Fig. 8, shows a double pointed pen usedwith the form shown in Fig. 7. Fig. 9 is a perspective view, and Fig. 10, is a plan View of another modification of my inven- V tion.

bined tubular font and pen holding ymember or receiver 2, and a de vice 3 that coacts-with the members 1 and 2 for frictionally holding the font or member upon. the member l and 'to aid in clamping he pen point wfrthin the said font or mem' er 2.

In the preferred form of my best shown in Figs. 1 and 5, 'the holder or handle portion 1 has a reduced shank l0 at the lower end, the upperface of which is iiattened and formed with undercut edges to slidingly receive the Vdevice 3 which is of metal and bent up to form side iiangcs for engaging with the undercut edges of the fiat face of the. tongue 10 as best shown in Y Figs. 3, 4 and 6.

The device 3 has a tongue like extension 11, the purpose of which will presently appear. rlhe member 2 comprises a tubular end 20 that fits over the shank 10 and the member 3, the outer end of which forms an invention,

tudinal passages f-Li are provided that open downwardly for infeeding the ink, see Figs. 1 and 2, and open upwardly so as to pro vide an' outlets, see the arrows on Fig. 1,

the said outlets being also produced by separating the members 1 and 2 as shown.

The sleeve or pen receiver 2 consists of a tubular inner end 20 that extends a sufficient lengt-h to provide the required socket for receiving the shank 10 of the holder 1. From the point where thetubular post 2O ends, the member 2 has its inner'side'doubly eoncaved as at- 21-21 and formed with a central con'vexed longitudinal groove 22 that merges with the concavedv portions 21-'21, as best shown in Fig. L1, and as is clearly shown in Figs. 1 and .2, the member 2 from the point where the tubular part 2O ends, has its inner or doubly concaved side made taperiiggto the pointend, that is, it is of gradually decreasing diameter, and its groove 22, which forms the feed channel for directing the ink to the pen, extends a lshort distance below the lower-front edge .fr

of the member 2 to provide a feed valley or duct 3l that leads theink. to the eye'50 of the 35 In Figs. 9,

pen 5, which may be of any of the ordinary types of writing pens.

The pen 6, when inserted into the member 2 1n the usual manner, slips between the front wall 25 of the member :2 and the4 tongue like extension 3 that slides upon and isfrictionally held by engagement with `the dove-tail tongue on the. shank end of the holder.

`So far as described, it will bereadily ap,- parent that when the pen is shaped np in the manner shown in Figs. l am a sinn ple and compact arrangement of the parts provided to which the ordinary type of pen can be readily7 attached.

By providing the connection fior the two -parts as stated, the pen, as also the pen and inlr receiver, can be readily slipped olf the handleV or holder' shank l, and since two well-defined air vente 4 4: are provided forim the escape o air contained in the receiver 2, it follows thatwhen the pen shown is placed in the receiver 2 and is Adipped into the well,- the ink will suck up and lill the receiver, sincethe air contained in, the said'reoeiver is allowed to freely escape through the vents 'fl-44 'at the top of the member 2.

` In Figs. i and 8 is shown a slightly modifled arrangement of my invention, and the said form is substantially like the other ex the tongue and groove-'slide connection, the

same as in the other terms. From the body portion, the member continues on. a reduced taper size and has its extension 3l bent outwardly from a straight line with Vrespect to the'holder l, as shown in Fig. 10, so that by simply turning the sleeve 2 on the shank said'sleeve can be turned on the shank and be adjusted so the pen projects from the 'handle at difl'erent angl-es, such arrangement being provided to meet the requirements of different writers with respect to the position best suited for writing. In this last form,

- shank l0 tapers with its opposite faces at different angles with respect to the member l so that by turning'themeinber 20 on the shank the said member assumes a diil'erent angled position shown in Figs. 9 and l0. 1

From the foregoing, taken in connection with the drawings, the construction 'and ad vantages of my improved type of pen will be readily apparent. llily reason of forming the holder with the central duct y that leads sired, the opening or ink inlet e may be increased byslitting the lower end of the hole endwise, as shown by s-s on Fig. 13. Having thus described my invention, what I claim and' desire to secure by Letters Patent, is:-

l. ln a pen of the character described, a pen holding member having the upper end tubular -and its lower end gradually tapering from'thetubular part'to the pen receiving end and a pen 'adapted t0 be slid into the lower front end of the said member; combined witha shank longitudinallyr grooved, and a clamping member shaped in cross section to slide on the shank and engage the grooves therein, said member being adapted to fit vinto the` pen holding lmember and to clamp the pen point.

2. In a pen of the character stated, the

combination of a handle having a shank, said shank having one face formed with longitudinal tongue, aclamp member whose under side is grooved to slide onto the said shank tongue, a pen holding member hav- .ing a tubular portion to lit over the shank a and the clamp member, and whose inner face tapers and 'is formed with a 4duct that extends to the pen receiving end thereof, and a pen point adapted to slip into the said holding member between its `front face and the clamp member.

3. In a pen of the character described, the combination of a handle having a shank, one face of which is formed with a longitudinal tongue whose opposite edges are undercut, a clamping device consisting of a member whose. under face is grooved to slip onto and interlock with the shank' tongue,

a pen point holder whose upper end is -tubular to slip over the shank and the clamp ing member, and whose remainder has its inner face tapering from the tubular portion to the pen polnt receiving end, a pen point adapted to slide into saidV4 end between the front Wall of the holder and the clamping ieinber, the holder having its rear face formed witha ductvv or feed channel that leads to the eye of the pen point, and means for admitting air into said pen-point holder at its upper end.

la A pen' of the character described, comprising the following elements in combination; a handle having a shank, a metallic pen-receiving holder adapted to be slid onto the shank, the .shank having channels that form air ducts when the holder is t upon lthe shank, the innerIface of the holder 13( being of a concavo conveXed shape in cross section and of a gradually reduced diameter to the pen receiving end and having an ink feed duct that extends its| 'full length, a pen point adapted to slide into the lower end of the holder and a member Shaped to slide onto and interlock with the shank, and to extend into the holder and clamp the pen point therein. l

A pen of the character'described, coinprising the following elements in4 combination; a handle having a shank, a metallic holder for securing the pen adapted to be slid onto the shank, the shank having channels that forni air ducts When the holder is fit upon the shank, the inner face `of the holder being of a concavo convexed shape in cross Section and of a gradually reduced diameter to the pen receiving end and hav ing an ink feed duct that extends its full length, a pen point adapted to slide into the lower end of the holder and a member shaped to slide onto and interlock with the shank, and to extend into the holder and' elainp the pen point therein, the said holder rear face tapering from said end to the penA point receiving end, said rear face having a concave convened shape in cross section to l'orin a central, longitudinally extended duct Whose delivery end projects beyond the pen receiving edge of the holder and is adapted to discharge into the eye of the pen point, and aconical sleeve having a groove to engage the tongue on the shank and having ite outer portion projected at an angle to the grooved end, said sleeve forming the receiver for the upper end of the pen point holder.
